摘要：
A method of operating a micro controller unit including maintaining a stop mode operation when a battery level detected n response to a first interrupt signal input from an external source is in a predetermined low voltage level range during the stop mode operation, and performing a normal operation corresponding to a second interrupt signal input from the external when a battery voltage level detected in response to the second interrupt signal is higher than the highest voltage level belonging to the predetermined low voltage level range.
